JOHN S. HALL, OF NEV YORK, N. Y.

OIL-CUP.

SPECIFICATION forming part of Letters Patent No. 427,312, dated May 6, 1890.

Application illed September 20, 1889. Serial No. 324.559. (No model.)

To all whom, it may concern:

Beitknown that I, JOHN S. HALL, a citizen of the United States, residing in the city, county, and State of New York, have invented certain new and useful Improvements in Oil- Cups, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to an oil-cup; audit consists in the combination of devices therein hereinafter particularly described, and as recited in the claims, whereby the advantages hereinafter specified are attained.

Figure l is an elevation of an oil-cup containing my invention. Fig. 2 is a plan of the same. Fig. 3 is a vertical central section of the same. Fig. 4. is a plan of my yimproved washer, hereinafter described. Fig. 5 is an edge view of same, and Fig. 6 is a plan of a modified form of the washer.

A is the reservoir of the oil-cup, vusually made of glass. v

B is the base furnished with the threaded shank for attaching the cup to a bearing. The base shown in the drawings is of the style known as sight-feed, but this form is not essential to my invention.

O is the top or cover of the reservoir, and is usually flanged at c to -fit over and inclose the rim of the reservoir, as shown. Vashers or packing-s, as shown at c and c2, are usually interposed between the reservoir and the base and top, respectively, and the parts are held together by a valve-tube D, which extends longitudinally through the cup and through an orifice in the bottom thereof, and is screwseated in the base and the top, as shown at CZ and d', respectively. The valve d2 is formed on the lower end of a stem D', which extends longitudinally through the tube, and is provided with a cap or handle d3 at its upper end, which is internally threaded to work on the threaded upper end d4 of the valve-tube above the top C, whereby the opening and closing of the valve are accomplished. In the top or cover C is formed an orifice c3, through which the reservoir may be fed with oil or equivalent lubricant without displacing the cover C.

At E is shown an arm, which is journaled at one end loosely upon the tube D, immediately above the cover C, and which extends to and preferably somewhat beyond the outer edge of the cover, and is of such width as to extend across and cover over the orifice c3 when it is swung over the saine.

The foregoing is a description of the features of oil-cups of this class now in general use, and to which I make no claim for novelty herein.

I will now describe my improvement.

E is a washer, which fits loosely upon the valve-tube D and rests upon the hub of the arm E fiatwise. Upon this washer I form a perimetal lug or teat e, extending therefrom at an angle to the plane of the washer and downwardly into a recess lor depression c4, which I form in the top or cover O to receive it.

E2 is a binding-nut on the valve-tube immediately above the washer, and serving,whenl screwed down upon the washer, to hold the washer and the hub of the arm F. to the cover C in position, as shown. When it is desired to swing the arm E so as to uncover the oriiice c3 in the cover, the washer, being held rigidly in position by its lug e, is prevented from being revolved on the tube by its frictional contact with the arm-hub, and hence is prevented from revolving and loosening the nut E2, while the arm is free to move, as stated. The nut being therefore once adjusted to exert the desired pressure or binding effect upon the arm-hub and washer, the arm may be swung on its journal without inlinencing the stability of the washer and nut in their fixed position. This result is greatly to be desired in oil-cups of this description.

While the lug e serves the purpose above described, it may also be made to serve as a stop to limit the movement of the arm E when it is swung to close the'orifice c3. This is accomplished by forming the recess o4 in the top C at such a point relatively to the location of said orifice c3 as will locate the lug e, when seated in said recess, at the limit of the movement of the arm E when it has swung toward and over the orifice. This is plainly shown in Fig. 2. I

The washer E may be provided with two lugs e and e', at such a distance apart and thus seated in corresponding recesses in the top C-one on each side of the orifice c--as IOO Will stop the movement of the arm E in one direction when the said arm is swung to close over the orifice and to stop the movement vthereof in the opposite direction when it is swung to uncover the orifice. The Washer thus constructed with two lugs is shown in Fig. 6.

By means of the described devices, constructed and located relatively to each other as set forth, I am enabled to provide at low cost an oil-cup in which the iilling-oriiicel in the top of the cup may be covered and uncovered by the movement of the swinging arm E without such movementof the arm disturbingr the fixed position of its bindingnut and Washer, an d'in Which such movement of the arm maybe limited or stopped in either or both directions.

Vhat I claim as my invention, and desire to secure by Letters Patent. is-

l. In an oil-cup, the combination, with the reservoir A, its top or cover C, provided with the orifice c3, the tube D, having` a threaded end extending above'said cover, and the arm E, journaled loosely on said tube end and adapted to close said orifice, of a washer E on said tube above said arm-hub, and having` an angular perimetal lug` e reaching past said hub and into and seated in a recess cL in the cover, together with a nut E2, Workin g on said tube end and binding` upon said washer, substantially as and for the purpose set forth.

2. In an oil-cup, the combination, with the reservoir-cover C, provided with an orifice c3, and having the threaded end of tube D'eX- tending above.it, of a Washer E on said tube end, provided with an angular perimetal lug e, seated in a recess c1 in the cover, and a nut E2, working on said tube end and binding on said washer, together with an arm E, journaled loosely on said tube end between said washer and the cover and of such extent or width that when it is swung to close over said orifice in the cover it will abut against and its movement be limited by said Washer-lug, substantially as and for the purpose set forth.

In an oil-cup, the combination, with the reservoir-cover C, provided With an orifice c3 and having the threaded end of tube D eX- tending above it, of an arm E, journaled loosely on said tube end and adapted to close said orifice, a Washer on said tube end above said arm-hub, and having the angular perimetal lugs c and c reaching past said hub, one on each side of said arm and into corresponding recesses in the said cover and adapted in location relatively to said arm to permit the arm to play between them when swung to open or close said orifice, together with a nut E2 on said tube end binding upon said washer, substantially as and for the pur pose set 'forthj JOHN S` HALL.
